CAR=DO0R FASTENER.

SPECIFICATION formingpart of Letters Patent No. 282,598, dated Au ust 7, 1883.

Application filed April 9, 1883.

\ be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part hereof, and in which- Figure 1 represents a front view of my fastener attached to a sliding car-door, and the same locked. Fig. 2 shows an end sectional view of Fig. 1. Fig. 3 represents my fastener attached to a pair of hinged and horizontallyswinging car-doors. Fig. 4 represents a plan view of Fig. 3, in which the doors are shown closed. Fig. 5 represents aplan view of Fig. 3, in which one door is shown partly open.

Like letters of reference indicate like parts. In the drawings, (t represents a bar or shaft extending across the width or length of the door, and fastened to the same in suitable bearings, Z, and provided onlits ends with hooks c, which enter into eyebolts or catches 9, attached to the side of the car. Said hook c is formed wedge-shaped or eccentric, so that its point may more readily take hold of the catch 1 and so that as the door closes with increasing resistance its power to overcome the same may be increased, and, also, that it may the more firmly hold the door when closed. To the center of the shaft a is attached a lever, b, by means of which the rod ais escillated or partially rotated on its axis, and near the end of said lever is attached to the door a staple, 6, through which a bolt, f, may be passed to hold the fastener closed; or a padlock may be applied.

\Vhen the door is hung on a sliding rail or track, k, and so as to rest on the outer side of the car, as shown at t in Fig. 1, the catch 9, on one side of the door at least, has to be sunk into the side of the car, so as to permit thev (No model.)

or the doors may be joined by a lap or bevel, as shown, or in any other well-known manner.

When it is desired to close the doors, they are swung in place, the lever I) being first thrown out, as shown in Fig. 5, so that the end of the hook 0 may catch in the eyebolt or catch 9. Said lever is then thrown over upon the fulcrum h and fastened. During this op eration the hook c, as it enters the catch g, draws closer to it, and so constantly increases its power. until the dooris closed.

When the door is to be opened, the back of .the notches (I, cut out of the door-frame, must be cut so that the hooks c, in opening, will press upon the bottom of them. The eyebolt answers both purposeseither to force the door open or to tightly close it.

.XVhat I claimas new is 1. A car-door fastener consisting of an oscillating rod, (1, provided with lever b and hooks c, constructed so as to give increasing force when closing the same, in combination with the catch 9.

2. The oscillating rod (1, provided with le ver 1) and eccentric hooks c, in combination with the catch r 3. The oscillating rod (1, provided with levcr b and eccentric hooks c, in combination with the catch g and staple e.

i. The oscillating rod a, provided with ]ever 1) and eccentric hooks c, in combination with the beveled doors 1 and 2 and parts 9 and e.

5. A car-door fastener consisting of a lOt capable of oscillating or rocking on its longitudinal axis, and provided with hooks 0, constructed so as to give increasing force when closing the same, in combination with the eyebolt or catch substantially as specified.
